I've bought a Samsung UA40D5003BR (LCD, LED backlight) 2 weeks ago. I also have a Samsung 40A550 (LCD, CCFL backlight). On the UA40D5003BR I have adjusted the backlight, brightness, power saving, basically everything I could to get the backlight less bright, but still it is way too bright. If you sit in front of the panel @ 90° you can see a dim blue-ish tint if no picture is displayed, but if you start moving off 90° the blue-ish tint becomes much brighter and really distracting and irritating. My 40A550 does not do that at all, not even if you look at it from 5°. Do any one of you have a UA40D5003BR and experience the same thing.
